12 Claims. (Cl. 19763) My invention relates to typewriting and like machines and particularly to margin stop mechanism. More specifically, my present invention relates to an automatically operated margin stop mechanism and also to the combination of such mechanism with the carriage return mechanism.

The main object of my invention, generally stated, is to provide comparatively simple and yet highly efficient means of thecharacter indicated.

A further object of my invention is to provide means of the character specified which may be embodied in the nature of an attachment in existing. machines without modifying, or materially modifying the .structural features thereof.

Another object of my invention is to provide an improved automatically operated margin stop which may be controlled from the carriage return mechanism.

Still another object of my invention is to provide a selectively controlled and automatically operated margin stop which will be moved to effective position only when the carriage return key is maintained depressed during the entire return movement of the carriage.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the fol- 30 lowing description and particularly pointed out in the appended claims.

one type of office recording in which machines embodying my invention may be used.

I have shown my invention in the present instance embodied in a combined typewriting and computing machine which from certain aspects may be like that disclosed in the application of F. A. Hart Serial No. 510,941, filed January 24, 1931. This machine is known generally as a Remington Electrified Bookkeeping Machine, and is equipped with. a power actuated carriage return mechanism of the type shown in the patent to F. A. Hart No. 1,978,997, dated October 30, 1934. In the present instance I have illustrated only so much of the said machine as may be necessary to arrive at an understanding of my invention in its embodiment therein.

While the devices of the present invention may readily be incorporated as an attachment in the machine referred to without modifying, or materially modifying the existing-structural features thereof, it should be understood that the invention is not restricted to use in the machine mentioned, but may be employed in typewriting, combined typewriting and computing and like ma.-

, chines generally, wherever found available.

From certain aspects of my invention it may be regarded as an improvement on the construction disclosed in the patent to F. A. Hart No. 1,967,437 dated July 24, 1934. According to the construction disclosed in this patent manually controlled means have been provided that will enable the operator, when desired, to arrest the carriage to the left of the position where ordinarily it is arrested by the operation of the automatically operating carriage return mechanism,

, tion to which the carriage will return, the operation of the mechanism being incidental to the actuation of the usual carriage return key, as will hereinafter appear.

I shall first describe some of the usual featuresof construction, including the power actuated carriage return mechanism, with which the devices of my invention are combined, and will then describe such devices. This will be followed by a description of two specific examples of a type of billing and oflice recording to which the use of the devices of my invention is adapted.

Referring now to the vdrawings, and particularly 2, it will be observed that the frame of the machine comprises a two-part base [5, corner posts It and a top plate H. In the present instance the usual carriage of 8. Remington accounting or typewriting machine, which comprises end bars l8, a rear cross bar l9 and a front cross bar 2), supports a cylindrical platen 2| and is shown mounted to travel over the top plate ii of the machine from side to side thereof, being propelled in the direction of its feed by the usual spring drum .(not shown) under control of the carriage escapement mechanism. Thus, the carriage is mounted in the usual manner to travel on crossed bearing rollers 22 received in oppositely grooved bearings of the rear and front cross bars l9 and respectively, and in fixed rear end front guide bars or rails 23 and 24 respectively.

At any point in the line of travel of the car-' riage, or automatically at the end of a line, the carriage return mechanism may be actuated to return the carriage to the right in positionto begin a new line of writing. The power actuated carriage return mechanism used in the present instance is shown in the above mentioned Hart Patent No. 1,978,997 and will now be briefly described.

As shown in Fig. 1, an upright shaft 25, which is preferably mounted on ball bearings, (not shown) is supported from the frame of the machine and has fixedly connected to the upper end thereof a pinion 25. This pinion meshes with a rack bar 21 secured to the carriage. The vertically disposed shaft 25 has a worm wheel 28 loosely mounted thereon and with which a horizontal'ly disposed worm 29 meshes. The worm 29 is fixedly secured to a horizontally disposed driven shaft 30 which may be connected to a main driving shaft 30* through a clutch 3|, said main driving shaft 30= being constantly rotated by means of a continuously running electric motor (not shown) mounted in the usual manner at the rear of the machine. A second clutch comprising two sections 32 and 32 is employed to effect an operative connection between the worm wheel 28 and the vertically disposed shaft 25, the section 32' belng'splined at 32 on the shaft 25. Both of the clutches 3i and 32-32'- are controlled by a-rock shaft 33 which is connected to said clutches, through clutch controlling, arms a and b respectively in such amanner that when said shaft is rocked in one direction the clutches will be simultaneously released and when the rock shaft is rocked in the opposite direction said clutches will be simultaneously closed. Thus, it be apparent that when the rock shaft 33 is .rocked'to close the clutches, the shaft 25 will be rotated and will efiect a return of the carriage, 5 as will hereinafter more clearly appear.

I shall now describe the automatically operated means controlled by the travel of the carriage for rocking the main control shaft 33, thus controlling the opening and closing of the clutches by which the motor is rendered effective to return the carriage and is rendered ineffective when the carriage has been returned.

Referring particularly to Figs. 1 and- 2 it will be observed that the front cross bar 20 of the carriage carries an adjustable line stop 34. An arm 35 extends into the path of movement of the stop 34 and is carried by a rod 36 supported at one end for limited longitudinal movement in a bearing opening in a bracket 31 secured to the frame of 20 the machine. The left-hand end of the rod 36 is pivotally connected, as at 38, to an upright arm 39 fixed near one end of a short rock shaft 40. To the opposite end of this shaft is fixed a'substantially horizontally disposed arm 4|, having 25 pivoted thereto a depending rod 42. The lower end of this rod is pivoted at 43 to an angular lever 44, which bears against a stop 44 when the parts are in normal position shown in Figs. 1 and 2 and is pivotally mounted on a pivot rod 45 30 adjacent a hub or bearing member 45- pinned or otherwise fixed to said rod. The pivot rod 45 is horizontally disposed and extends across the machine at apoint below a control box 46 which is secured to the left-hand side of the machine by 35- means of screws 4'! and is the housing for part of the control devices for the carriage return mechanism. An upright aim of the lever 44 is operatively connected to a link or rod 48 by means of a laterally projecting pin 49 provided on said le- 40 ver and received in an elongated opening 50 in the link 48. The rod 43 carries a hook-like end portion 5| and is guided by a guide member 52 secured to the control box. The hook-like end of the member 48 is adapted to engage behind a pin 46 53 that projects laterally from a holding pawl 54 pivoted at 55 to the control box, said holding pawl being urged in a counter-clockwise direction by a contractile spring 56 which is connected at one end to the pawl 54 and at its opposite end 50 to the link 48. The upper free end portion of the pawl 54 has a hook-like engaging portion 51 adapted to hook over the free end of an arm 58 secured to and projecting forward from the control shaft 33 and urged-in a counter-clockwise 56 direction as shown in Fig. 2 by means of a contractile spring 59. Movementof the arm 58 in a counter-clockwise direction tends to turn the shaft 33 in a corresponding direction thereby effecting a closing of the two clutches 3| and 60 32-42- to render the carriage return mechanism effective. The arm 58, however, is held down in its lower position, where the clutches are maintained released, by the engagement of the pawl 54 with the free end of said arm. When, however, 66 the carriage reaches the end of the line the stop 34 will engage the arm 35 and shift it until it coacts with the bracket 31. The construction of the above described parts is such that when the arm 35 is moved into contact with the bracket 31, 70 the link 48 will be drawn through the intermediate connections to .the right as the parts are shown in Fig. 2. This results in moving the pawl 54 out of engagement with the arm 58 so that said arm may be moved upward by the spring 53 to effect a closing of both of the clutches a'nda return of the carriage to the right as hereinbefore described.

Thismovement of the carriage to the right will continue until a left-hand margin stop 6| contacts with an arm 52 carried by a longitudinally movable rod 83 supported at one end in a bearing opening in the bracket 31. The opposite end of this rod 83 is pivotally connected to an angular lever 84 which is pivoted on the rock .shaft 48. The horizontally disposed arm of the angular lever 64 is connected to a depending link 65 the lower end of which is pivoted at 66 to an angular lever 61 pivoted at 68 in the control box 46. The other arm of this angular lever is pivoted at 58 to a longitudinally movable bar 10 supported for sliding movement at its left-hand end, as the parts appear in Fig. 2, by a pin 1i that is received in a slot '12 in said bar. The lower edge of the bar is provided with a cam face 13 that coacts with an anti-friction roller 14 carried by the arm 58. A returning spring 15 encircles the pivot 68 and bears at one end against the side of the control box 46, and at its other end bears against an arm of the angular lever 61 tending to turn said lever in a clockwise direction as shown in Fig. 2.

The effect of moving the rod 83 to the right through the coaction of the margin stop 6! with the arm 62 is to elevate the connecting rod 85 and thus effect a downward longitudinal movement of the bar 18 from the position shown in Fig. 2. This results in bringing the cam 13 into cooperation with the anti-friction roller 14 to thereby depress the arm 58 to a position where the retaining pawl 54 may coact therewith to lock the arm in its depressed position. It will be apparent that this downward movement of the arm 58 to its locked position will effect a clockwise movement of the rock shaft 33 to open the two clutches 3| and 32-42 and free the carriage from the control of the motor as hereinbefore described.

In addition to the means for automatically returning the carriage in the manner hereinbefore indicated, there is provided the usual carriage return finger key 16 by an actuation of which the carriage may be returned by the motor from any point in the travel of the carriage. As shown in Fig. 11 the key 18 is carried by a lever 11 which is mounted on the rock shaft or pivot rod 45 at the right-hand side of the machine. If desired, a second carriage return key '16 functioning for the same general purpose as the key 18 may be disposed at the left side of the machine. As shown in Fig. 2, this second carriage return key 18* is carried by a lever 11 which is loosely mounted on the bearing member 45*. A rearwardly extending crank arm 18 is fixed on the inner end of the bearing member 45 adjacent the lever 11 and is provided with a laterally pro- Jecting pin 19 which coacts with an arm 88 on the lever 44. The construction is such that a depression of the carriage release key '18 will move the lever 44 through the intermediate operative connections in a clockwise direction; as the parts are shown in Fig. 2, thereby releasing the holding pawl 54 and bringing about a closing of the clutches 3|, 32-42 to eflect a carriage return in the same manner as the automatically wntrolled means hereinbefore described.

The manner in which the carriage return key 18- effects a return of the carriage will be described hereinafter. It will be understood, therefore, that the operator may with the aid of the i the exception of the carriage return key 18, is

of usual construction and is shown in the above mentioned Hart Patent No. 1,978,997. By my present invention I provide auxiliary means in the nature of attachments to function in combination with the features referred to and which auxiliary means will now be described.

Referring particularly to Figs. 1, 4, 5, 6, and 7, it will be seen that a carrier, designated as a whole by the reference numeral 82, is constructed and adjustably mounted in a manner similar to the ordinary margin and line stops 6! and 34 respectively, being provided with looking teeth 83 (Fig. 4) adapted to engage with teeth 84 of a rack bar 85 carried by the front rail 28 of the carriage. The carrier has a cut-out or channeled portion 86 in which a depending flange 81 on a detachable top section 88 of the front carriage bar 28 is received, said top section 88 being positioned above the rack bar 85 and carrying the usual scale 88. At the right-hand end of the channeled portion 86 the width thereof is substantially equal to the thickness of the flange 81, and the rear wall 88 slopes outwardly from this point so that the width of the channel gradually increases toward the left-hand end thereof, as 80 shown in Fig. 4. This construction allows and provides for a fore and aft rocking movement of the carrier around one end thereof on the flange 81 in order to move the teeth 83 out of and into engagement with the rack bar teeth 84. A leaf spring 91 is secured to the carrier at one end in a notch 92 and bears at its free end against the inner face of the flange 98, as shown in Fig. 4. Thus, the center or bowed portion of the spring bears against the rear face of the flange 81 and a force is exerted to swing the carrier 82 rearward with a pivotal movement and maintain the teeth 83 thereon in engagement with the rack bar teeth 84. To release the carrier from the rack bar teeth it is merely necessary to swing the left-hand 'end thereof forward to disengage the teeth 83 from the rack bar when it may receive a sliding adjustment along the flange 81 to any desired position along the carriage.

As shown in Figs. 4, 6 and 7 the left-hand end of the carrier 82 is provided with a vertically disposed groove or way 84 whichis of dove-tail formation in cross section and is adapted to receive a correspondingly shaped intermediate margin stop 85. The margin stop 95 is given a vertical sliding movement in the way 94 into and out of effective position by means of a control lever 96 which is pivoted at 91 on the carrier 82. This lever, in the present instance, is substantially horizontally disposed and is slotted at 98 for the reception of a pin 98 carried by the margin stop 85. Fig. 6 shows the stop in its projected or effective position, said stop being limited in its movement to this position by contact of a pin 188 provided on said stop with the 05 lower wall of a notch iOl provided in the carrier 82. Movement of the margin stop to normal position shown in Fig. 1 is limited by Contact of a pin I82, provided in the control lever 86 to the right of the pivot 81, with an engaging 70 or stopping edge I03 formed at the right-hand end of the carrier 82. Said stop 85 is resiliently held in this normal position by means of a contractile spring )4 attached at one end to the control lever 86 and at its other end to a pin I85 76 provided in the carrier 82, said spring I04 tending 'to turn the control lever 96 in a clockwise direction, as the parts are depicted in Fig. 6 for example.

As hereinbefore pointed out, according to my present invention, I have provided means for automatically and selectively moving the margin stop 95 from ineffective to effective position.

. Such means comprises, in the main, the control lever 98 which is provided with an outwardly bent flange, cam or contact surface I08, and an actuating member or lever I08 mounted on the stationary framework of the machine. When the actuating member I08 is'moved to effective position and the carriage is returning to the right the contact surface I05 will come into engagement with said actuating member, and such contact will cause the control lever 96 to turn in a counter-clockwise direction, as shown in Figs.

'1 and 6, to move the margin stop 95 to effective position.

I have provided two dilferent forms of mechnisms for controlling the movement of .the actuating member I08 to its effective position, one

-" of which constitutes a separate and distinct train of mechanism from said actuating member to the carriage return key 16 provided at the left-hand side of the machine, while the other train of mechanism includes the usual existing manual controls, including the key I8, for the arm 35 and connected parts. In this last mentioned form of construction the movement of the actuating member I08 is controlled directly from said arm 35. I shall now describe the first form 1 of controlling mechanism for the actuating member I08 in which said member is moved to effective position by a separate and distinct train of connections to the carriage return key 18 provided at the left-hand side of the machine.

Referring particularly to Figs. 1,2 and 4, it will be observed that the actuating member I 08, in the form of an angular lever, is pivoted at H to the stationary framework of the machine, in

-the present instance to the front guide rail 24 and substantially at the center thereof. Actually the actuating member I08, or the pivot IIO for said lever, is located to the right of the center of the machine a distance substantially the same position it will always contact the-"surface I08 when the carriage is moving to the right no matter where the carrier 82 is mounted or adjusted along the carriage. However, the adjustment of the carrier 82 along the carriage determines the point in the return movement of the carriage where the margin stop 95 will be rendered effective, assuming that the actuating member I08 is in the operative position.

The downwardly extending arm III of the angular lever I08 is loosely pivoted at II2 to a link II3 which is adjustably connected by'a threaded connection, at II4, to an arm II5 which occupies a position at the front of the machine below the arm 35. A pin II 6 connects the arm 5 to a substantially horizontally disposed rod II! which is supported at the right-hand end thereof, near the connection to the arm I I5, in a. bearing opening in the bracket 31. The left-*- hand end of the rod I I1 is pivotally connected, as at H8, to an upright arm H9 pivotally mounted 5 on the short rock shaft 40. The short upright arm II 9 is one arm of an angular lever, the other substantially horizontally disposed arm I of which has pivoted thereto through an elongated pivot or stud I2I 2. depending rod I22. At its lower end the depending rod I22 is pivoted by means of an elongated pivot or stud I 23, as shown in Fig. 3,-to a lever I24 which is loosely pivoted on the hub 45. As shown in Fig. 2 the lever I24, is angular in shape and at the apex thereof is provided with a hook-like engaging portion I25 which is adapted to engage with a pin I26 provided at the right-hand end of the member 48. Below the pivot I23, the lever E24 is connected to the carriage return lever TI- by 20' means of a link I2I secured to the levers I24 and 'II by any suitable means such as the screws I28. Thus, It will be seen that when the carriage re turn key 16 is depressed and turns on the hub 45, it will, .by means of the link I21, effect adownward movement of the rod I22 and a clockwise movement of the lever I24. Such a. movement of the lever I24 will eifect a release of the arm 58 from the engaging portion 51 of the lever 54 and the carriage will start' its return move- 30 ment to the right. Simultaneously therewith the rod I II will be moved to the left to cause the an-' gular lever or actuating member I08, to turn in a clockwise direction about its pivot I I0 from the position shown in 1 to that shown in Fig. 6. It will be understood, therefore, that when the I key Iii is depressed, and maintained in depressed position, it will effect a starting of the return movement of the carriage and incidentally will move the actuating member I08 to the position shown in Fig. 6. Thus, with the carriage moving to the right and the actuating member I08 maintained in its vertical position the contact surface I06 of the lever 96 on the margin stop carrier 82 will come into engagement with the actuating member I08 to move the margin stop 95 downward to its effective position. During the return movement of the carriage the margin stop 95 will contact the arm 62 and, due to the movement of the carriage to the right, will move 597 said. arm 52 also to the right until stopped by contact with the bracket 31. This will cause a downward longitudinal movement to the right of the member I0 in the control box 46 to eifect a downward movement of the arm 58 and a consequent disengagement of the clutches 3| and 32-442 to stop the action of the carriage return mechanism. In this manner the carriage will be returned and arrested in a position determined by the adjusted position of the margin stop 95 and in every instance the clutches will be auto matically released and the carriagefreed from control of its power actuated return mechanism irrespective of the position to which the margin stop 95 may be adjusted. It will be apparent that while the return key I6 is held in its depressed position the member 48 will hold the pawl 54 in a released position to the right of that shown in Fig. 2 where it will not be able to engage the free end of the arm 58 when said arm is returned through the action of the-cam I3 and roller 14 as explained above.

-' Therefore, when the carriage is finally brought to an arrest at the position determined by the automatically operating margin stop 95, the re- I it willbe observed that an turn key It may be released to allow the hooklike engaging portion 51 of the lever 54 to come into engagement with the free end of the arm 58 so that the carriage return mechanism will remain out of operation during the letter space movement of the carriage to the left for anotherline of work.

Moreover, it will also be apparent that when the member 48 is moved to the right under action of the carriage return key 18 and lever I24, due to the pin and slot connection between the lever 44 and member 48, the train of mechanism between said lever 44 and the arm 35 will be unaffected and is in a condition to be actuated by the line stop 34 when during the next advance movement of the carriage it reaches the end of actuating member I08 to connect it for operation with the carriage return key I6 have been omitted and yet the same results as described above may be attained. It is obvious, therefore, that the resultant construction is far simpler than that described above and may be regarded as the preferred form of my invention.

In the following description of this simplified and preferred form of my inventionthe parts which are the same as those described above for the first form of my invention will bear corresponding reference numerals.

Referring particularly to Figs. 9, 10 and 11, actuating member I08, which may be the same as the angular lever I08, is pivoted at II0 to the front guide rail 24 in substantially the same manner and in the same place as the lever I08 described above. The downwardly projecting arm Ill of the angular lever or actuating member I08 is pivoted with a loose connection at H2 to a link 3*, said link H3 being in turn adjustably connected, as at N4 to a downwardly and forwith the aid of the Skip key tabulator hereinconnected to, or in the present instance formed integral with, an arm 35 which has the same purpose as the arm 35 described above. The arm 35 is secured to the rod 36 at the righthand end thereof and under the infiuence of said rod 35 or by contact with the line stop 34 may be moved to the left until stopped by engagement with the bracket 31. Due to the addition of the arm I30 to the arm 35*, it may be found advantageous to provide a guide pin I3I on the arm I30 which may be received in a bearing opening in the bracket 31 to further stabilize and guide the member '55 in its movement.

It will be recalled that, as described above, when the carriage return key 16 shown in Fig. 11 is depressed, the member 18 will be raised to turn the angular lever 44 in a counterclockwise direction. Such movement of the angular lever 44 will effect throughintermediate connections a leftward longitudinal movement of the rod 35 which will result in drawing the member 35 I30 to the left and thereby move the actuating member I08 in a clockwise direction about its pivot IIIl into effective position. Simultaneously with the moving of the actuating member I08 to effective position, the member 48 will be drawn to the right (in Fig. 2) to bring about a releasing of the clutches and thus start the carriage in its return movement to the right.

Thus, it will be apparent that if the carriage return key I6 is held in its the actuating member I08 vertical or effective position so that during the return of the carriage the contact surface I06 will be engaged thereby to move the margin stop 95 into position where the engaging portion 10 thereof will subsequently come into contact with the member 62 to bring about an arrest of the carriage and a freeing of it from control of its power actuated return mechanism. If, however, the carriage return key 16 is not held in 15 its depressed position but is merely given a quick actuation to start the return movement of the carriage, the actuating member I08 will be inefiective to bring about any movement of the margin stop 95 since said actuating member I08 20 will not be retained in a position to contact the surface I06. Therefore, the margin stop 95 will move past the actuating member I08 and the ordinary margin stop IiI will come in contact with the arm 62 to effect a stopping of the re- 25 turn movement of the carriage in its usual position of arrest and a freeing of it'from control of its power actuated return mechanism in the will remain in its usual manner.

It will be seen that by the present construc- 30 tion of the actuating member I08 and. its manner of connection to the modified arm 35 --I30 I may eliminate the use of a lefthand carriage return key 18 lever I24, link I21, rod I22 and the rest of the connections to the link I I3 shown 35 in Figs. 1, 2, 4, 5 and 6, as described above. Moreover, as shown in Fig. 11, by eliminating the return key 16 the pin and slot connection 49-50 between the angular lever 44 and the rod 48 may be omitted. However, if for any reason 40 it is found desirable to have the actuating member I08 or I08 for the automatically controlled margin stop 95 operated from a separate key, such as the key 15, it could be done in the manner described above in accordance with the 45 first form of my invention.

Having thus described the construction and operation of my selectively and automatically controlled intermediate margin stop, I shall now describe two specific types of ledger sheets for 5C use in department store accounting which illustrate certain only of the many applications of a machine embodyingmy invention.

In Fig. 12 there is shown the usual type of department store ledger sheet in which the amount 51 of the charge for any particular item is inserted on said sheet after the description of the item. The showing in this figure is in the na-' ture of a diagram and is more or less self-explanatory, but I shall nevertheless describe it 6 briefly to point out particularly the role which Y the devices of my invention play in a set-up of equipped with automatic and skip key tabulator mechanism of the type disclosed in the application of Dodge and Philbin filed August 11, 1934, and bearing Serial No. 739,384. The No. Remington electrified bookkeeping machine is also provided with a vertical totalizer for each column in which entries are made and two cross totalizer-s for totaling and/ or proving such entries. In the drawings and in the following description the amounts are merely for purposes of illusdepressed position, 5

'totalizer, or particularly into the totalizer for the Balance column. The carriage is thenreturned to a position for starting a line of entries by giving the carriage return key a quick actuation. This will move the carriage to the right until the margin stop 61 contacts the arm 62 to bring the carriage to rest momentarily, when it next will be automatically tabulated by said Dodge and Philbin tabulator to position for the first digit of-the Previous balance, which it has been assumed is 25 00. This amount is printed and at the letter space after the last zero is printed, the carriage vis again automatically tabulated into the center of the Date column where the date is printed in a single stroke by the usual date printing type bar, and after this print,- ing the carriage is again automatically tabulated to the Description column where the description of the merchandise or type of entry, such as Cash, Credit etc., is made. Since the amount of space taken up by this item may vary, the automatic tabulator is not used to move the carriage into the Charges column. Thus, said carriage is moved to the Charges column by an actuation of the usual palm tabulator key. The

operator then enters the amount 2 25 and depresses the carriage return key. If another item is to be entered for this same date,.the operator holds the carriage return key depressed to cause the carriage to stop at the intermediate margin stop position in a manner that has been hereinbefore described. In the present instance, the intermediate margin stop is set for the begin-' ning of the.Description column as indicated in Fig. 12. The rest of the entries to be made are accomplished in the usual manner, and the carriage is moved from column to column in a-manner indicated in Fig. 12 by the use of the dotted lines and arrows and the descriptive matter inserted at the bottom of Fig. 12.

If only one entry is to be made under the first date, instead of returning the carriage to 'the Description column, said carriage is tabulated with the aid of the Skip key tabulator hereinbefore referred to, to the Balance" colunm in the manner indicated after the second entry of 2 30 in Fig. 12. It will be understood that by the use of the automatically controlled intermediate margin stop of my invention it is not necessary to return the carriage to its extreme righthand position and then subsequently tabulate it to the Description column, but the carriage is automatically stopped in its return movement, as explained above, in the proper place for starting the description of the second item. Therefore the work performed on the machine may be affected more rapidly than heretofore, with less labor and effort on the part of the operator and with less wear and tear on the machine.

In Fig. 13 I have shown a different form of ledger sheet for use in the same type of department store accounting, the chief difference from the ledger sheet shown in Fig. 12 being that the Charges column has been shifted to the left of the Description column; In practice it has been found that 'usually many more purchases than one are made on a single day, and by moving the Charges column to this new position the work of making the entries is greatly facilitated and the entire billing operation is made faster as will hereinafter appear.

With this new form of ledger sheet, after the Balance brought forward has been entered, the carriage is returned with the aid of the carriage return key for the entry of the Previous balance and Date in the same manner as has been described above in connection with Fig. 12. The carriage is then automatically tabulated to the first digital position of the Charges column is and the amount 2 25 is entered and the car riage again automatically tabulated to the Description column. After inserting the necessary descriptive matter in this column, if another charge is to be made on the same day, the elec- 15 trio carriage return key is'depressed, and held depressed, to return the carriage to the position of the intermediate margin stop 95, in a manner as described above. As shown in Fig. 13 the intermediate margin stop is set for the next letter 2') space position after the printing of the Date, so that upon reaching this point the carriage will be automatically tabulated again into the Charges column. It will be apparent that the intermediate margin stop is set in this position so that the cross truck will be picked up by the vertical totalizer for the Charges column and will thus carry the cross totalizers-into the computing zone.

When the totalizer for the Charges column :1) has been carried into the computing zone in this manner, the second entry of 2 30 is made and the carriage is again automatically tabulated to the Description column'for the entries to be made therein. The rest of the operations are done in the usual manner and as indicated in Fig. 13. As with the form of ledger sheet shown in Fig. 12, the use of the intermediate margin stop in the present instance decreases to a minimum all lost motion in preparing a ledger sheet 49 of this general type. A

From the foregoing description it will be apparent that I have provided a comparatively simple and yet highly eflicient margin stop which may be selectively and automatically controlled 45 from the carriage return mechanism and will be moved to effective position only when the carriage return key is maintained depressed during the entire return movement of the carriage.

While I have described my invention in the 50.

present instance in combination with power actuated carriage return mechanism, it should be understood that from certain aspects of my invention it may be embodied in a machine in which the carriage is returned by hand. For ex- 55 ample, by breaking the connection between the key l6= and the power actuated carriage return mechanism, by the elimination of the angular lever I24, for example, we have a construction in which the intermediate stop control mecha 60 nism will properly function on the depression c5 the key Hi and the return of the carriage by position from any of its adjusted positions, said means comprising a controlling lever acting upon said stop and movable therewith, and an actuating member for actuating said controlling lever during movement of the carriage.
